ROBERT M. KEYES, OF WEST ALLIS, WISCONSIN.

MOTOR.

Application filed August 19, 1915.

To all whom it may concern:

Be it known that I, ROBERT M. KEYES, a citizen of the United States,residing at West Allis, in the county of Milwaukee and State of-Wisconsin, have invented certain new and useful Improvements in Motors;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to motors, and more particularly to a motoradapted for attachment to row boats, or the like, and the primary objectof the invention is to provide a motor, which includes an internalcombustion engine, the explosion chamber of which is submerged withinthe water, so as to provide for the efficient cooling of the motor,eliminating the necessity of the employment of a water pump, mechanismfor operating the pump, and for a water jacket surrounding the explosivechamber of the engine.

Another object of this invention is to construct a motor as specified,so that the en tire motor and the boat propeller, which is associatedtherewith, can be turned completely around, by means of the starting.and steering handle, thus making t pos-' sible to reverse the directionof travel of the boat without stopping, slowing down, or changing thedirection of rotation of the engine and propeller.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like andcorresponding parts throughout the several views, and in which Figure 1is a side elevation of the improved motor, showing the same applied tothe rear end of a boat, and further showing parts'of the motorconstruction broken away, and

structure 3. The bracket structure 3 includes a substantially U-shapedclamp A, which extends over the board 2 and is held in firm engagementtherewith by means of a tightening bolt 5. An arm 6 is formed upon oneleg of the U-shaped member 4, and it has a collar 7 formed thereon. Anangled arm 8 extends downwardly along the rear end of the boat from thearm 6, and has a collar 9 secured to the outer surface of its lowerangled end. A plate 9 is formed upon the arm 8, and engages the surfaceof the rear of the boat, for co-acting with the U-shaped section 1 forsecurely holding the bracket structure 3 firmly in position against andconnected to the rear end of the boat 1. The collars 7 and 9 encompass avertical housing or cylindrical shaft 15 rotatably journaled therein.The

crank shaft 15 has a beveled gear 16 mounted thereon, which meshes witha second beveled gear 17 The beveled gear 17 is a half gear and ismounted on a shaft 18 which extends vertically through the casing 11,and has a steering handle 19 connected to its upper end. The steeringhandle 19 is composed of two sections 20 and 21, which are pivotallyconnected at their inner ends, to the upper end of the shaft 18, as isshown at 22, for movement vertically, as is shown in dotted lines inFig. 1 of the drawings.

The crank shaft 15 has the piston rod 23 connected to the wrist 24 ofthe crank portion of the same. The piston rod 23 has a piston head 25mounted theron, which is slidably mounted within a cylinder 26. Thecylinder 26 is supported by the housing 12, and extends upwardlytherefrom, and forms the combustion chamber of the motor.

A gasolene or volatile fuel retaining tank 28 is supported by the casing11, and it has a pipe 29 communicating with the lower end of the same,and extending a short distan'ce downwardly from the oil retaining tank,exteriorly of the casing 11, after which it is bent inwardly and extendsinto the casing 11, and downwardly therethrough, to the housing 12. Thepipe 29, which feeds the fuel from the tank 28 to the chamber of thecylinder 26,-extends a short distance through the housing 12, andupwardly=out of the same, communicating with the interior of thecylinder 26, as is shownat 30. Any suitable type of valve mechanism maybe utilized for controlling the flow of the fuel into. the cylinder 26.A mixer or carbureter 31 is interposed in the section of-the pipe 29.which extends downwardly from the tank 28, and outside of the post 11.

The cylinder 26 has a spark plug 81 of ordinary construction,communicating jwith the upper end of the same, which spark plug isconnected, bymeans of electrical conductors 32, to a magneto 33, whichis carried by the casing 11. The wires "32 are insulated by water-proofmaterial, so as" to prevent the short circuiting of the device,

when the wires extend downwardly through the water in which the boat: ispositioned. A timing lever, 31 is provided for regulating or controllingthesparking ofthe en gine. A casing 35,'which is constructed ofwater-proof material extends over and encompasses the which protrudesout of the cylinder 26,'so as to prevent water from engaging the sparkplug and rendering the same inoperativel When the improved motor isapplied to a row-boat or the like, the cylinder 26, and the housing 12are positioned beneath the surface of the water inwhich. the boat ispositioned, so that the water will act as a cooling agent for coolingthe cylinder 26 during itsoperation. The crank shaft 15 has a propeller36 mounted upon one end of the same,

which is rotated by the rotation of the crank shaft 15, 1 through thewater.

cal casing 11 is rotatably carried by the collars 7 and 9, so that theentire motor may be moved in'an arc, for steering the boat 1. The upperend of the'post or casing 11 is provided with notches 37, which arepositioned diametrically opposite of each other, and are adapted forreceiving portions of the sections 20 and 21 of the steering handle 19,for rotating the casing and consequently the housing 12, and the variousmechanisms connected to the casing 11 of the housing 12, for controllingthe direction of the boat, by varying the angle of travel or position ofthe entire motor structure.

Vhen it is desired to crank-or start the engine, the sections 20 and 21are moved upwardly into the position indicated in dotted lines in Fig. lof the drawings, so that they will be positioned out of the notches 37.and

portion ofthe spark plug 31' an internal combustion connected to saidcrank shaft and supported for driving the boat The post or cylindritheshaft 18 is rotated, which rotates the crank shaft 15 and impartsinitiative rotation to the propeller 36 and also initiative operation tothe piston 25, for starting the motor. The exhaust of the motor passesthrough an exhaust upwardly through the casing ll'to a position abovethe upper surface of the water.

From the foregoing description taken in connection with the accompanyingdrawings the advantages of construction and of the method of operationof the improved motor will be readily apparent to those skilled in theart to which this invention,appertains and, while in the foregoingdescription, the principle of the operation of this invention has beendescribed together with various features of construction, it is to beunderstood that certain minor features of construction, combination'andarrangement of parts may be altered to suit practical conditions,provided such alterations are comprehended within the scope of what isclaimed.
